Title: Compositions and methods for cleaning a wellbore prior to cementing
Filed: 2012-03-21
Abstract: Wellbore-cleaning compositions comprising microemulsions are useful during cementing operations. The microemulsion solvent may be selected from the group comprising methyl esters and ethoxylated alcohols. The microemulsion surfactants comprise a water-wetting surfactant, a cleaning surfactant, an emulsifying surfactant, a non-ionic surfactant and a non-ionic co-surfactant. The wellbore-cleaning compositions may be pumped alone, ahead of a conventional spacer fluid or scavenger slurry and behind a conventional spacer fluid or scavenger slurry. In addition, the wellbore-cleaning composition may be incorporated into a carrier fluid such as (but not limited to) a conventional spacer fluid or scavenger slurry. The resulting fluid mixture may be pumped as a spacer fluid.

Title: Handles for wrapped packages
Inventor: COLLINS BRIAN DAVY
IPC: B65B61/14
Filed: 1985-08-02
Granted: 1989-06-01
Abstract: An article (2) is wrapped in three plastics films (1, 4, 5) which are secured together at or near the bottom of the article by heat sealing using heat sealing jaws (9 and 13). The films (1,4,5) are then conformed to the shape of the article (2) by e.g. heat shrinking using hot air blower (16). One of the films (5) has different properties from the others and conforms differently so that it forms a handle for the wrapping. Strength of attachment of the handle is achieved by the combined effect of the heat seal (3) and the "tack" of the plastics films (4, 5) along the sides of the article.

Abstract: The healing of wounds is promoted by contacting the wound surfaces with a suspension of collagen and a glycosaminoglycan that is chemotactic for fibroblasts and/or endothelial cells. Typical glycosaminoglycans that exhibit the desired chemotaxis are heparin, heparan sulfate, and alginate. Two or more glycosaminoglycans can be present in the suspensions. Collagen is present in the suspension in the order of 7-10 mg/ml; while the glycosaminoglycan is present in much lower concentrations, e.g, 250-350 µg/ml. Application of the collagen/glycosaminoglycan suspension to open wounds greatly increases the rate of healing.

Granted: 1991-05-29
Abstract: Method for the preparation of an article from a blend of at least two molecularly compatible polymers by treating the blend with a solvent which is a solvent for one of the polymers and a non-solvent for the other. The solvent can be removed while the article is restrained from undergoing substantial shrinkage, in which case a microporous article is obtained. Alternatively, the solvent can be removed while the article is permitted to shrink. In this case high shrinkage force (also referred to as recovery force) results which can be utilized to apply the article to a substrate. The final and intermediate articles are novel. In a preferred embodiment, the invention provides a microporous article having an average pore size of about 0.005 microns to about 1 micron.
